How to re-enable FF 29 add-on compatibility check

Several weeks ago I installed FF 29.0.1 on two virtually-identical XP systems. I've been carefully maintaining extensions, settings, etc., in parallel on both systems.
Initially, my primary system told me if an extension in my search list was incompatible with 29.0.1, and presumably that's what I want to happen.
However, I recently installed a couple of extensions, that seemed to work okay. (I had downloaded the installers, and then installed them from the files.) Then, when I tried to install them from the same files on the second system, it told me that they were incompatible with 29.0.1, and that they could not be installed.
I want to re-enable the compatibility check on the system on which it seems to have been turned off. I've searched FF forums at length, but can't find any information on about:config or other settings that might affect this.

The error message I've been getting on one system when trying to install certain extensions is a small drop-down box from the green extensions manager icon near the upper left of the screen. However, it disappears when the "print screen" button is pressed, and does not appear in the captured image. I've noticed that kind of quirk on some other websites. So it seems to be impossible to get an image of the message. The message can be re-displayed, but not printed, by clicking on the green icon. However, the text of the message says, "<extension-name> could not be installed because it is not compatible with Firefox 29.0.1." Note: It is easy to reproduce this message by temporarily turning on extensions.strictCompatibility, and trying to install some older extensions.
In any event, the system on which I was getting the message is now behaving identically to my other system, apparently without any settings changes. Therefore, I feel that it was a persistent, but temporary, glitch that may have been fixed by a reboot. Therefore, the problem seems to be resolved.

Every time I start Firefox 8.0.1 it repeats the add-on compatibility check

Hi there
I'm using Vista and since updating to Firefox 8.0.1 every single time I start Firefox it repeats the add-on compatibility check.
I tried starting with add-ons disabled, deleting update files, started with different profile, nothing.
Is this a bug and we have to wait for another update or if it can be sorted I would appreciate some help please.
Cheers

Go to Firefox/Help/Troubleshooting, and in your Profile Directory/Open Profile Folder. Close Firefox (File,Exit) and on your Profile Folder look and delete this file "Pref.js" and any other "pref" files in there. Start Firefox and your preferences are reset to default. Go to Options and customise your preferences as you had before.

Everytime I open Firefox after the last update, it runs an add on compatability check and opens two tabs. One tab is the firefox "latest update faq" page and the other tab is the set homepage. This is very annoying, how do i make it stop???

when it checks add on compatability every time, its starting to get a little annyoning. I like firefox but am about to uninstall it.

See this article for some suggestions: [[Firefox has just updated tab shows each time you start Firefox]]

Prevent add-on compatibility check on 1st run

i am using a predefined prefs.js file with '''updates disabled''' and '''compatibility check false''' for add-ons as well
however each time i run firefox for the first time , i see a progress update window saying: checking comparability of add-ons
its important that i do not see this at all. any inout, anything else to look into the pref.js file?
i already have extensions.checkCompatibility.3.6 set to false and updates disabled.
odd thing is when i launch FF, i see all the correct options configured, and upon relaunch this does not happen. seems its during the first time the userprofile is launched
FF 3.6.17

that did not work
i ended up adding user_pref("extensions.update.url", ""); to my pref.js, so now when the browser launches for the first time, i see a blank window for less than 1 sec. which was an acceptable solution..
Thanks

How can I enable TOR with add-ons?

I want to use TOR on latest stable version of Mozilla Firefox.
I research on internet but I could not find tutorials about it. Because everyone suggest Tor Browser Bundle. But I don't want to use it, because it does not update itself and no updates means no security. I can not update it manually each time :(
So I want to use Tor with open source plug-ins and/or extensions. I don't want to install any app on my operating system.
How can I do it?
I try this:
I install Torbutton 1.5.2 extension from torproject's official web site. I set the "use custom proxy settings" from Torbutton's options.
Torbutton settings:
http://i57.tinypic.com/2vs1zx1.jpg
Firefox network settings:
http://i62.tinypic.com/2nlae1l.jpg
But it does not work.
I will be happy if someone can help me.
Thank you

Sorry, the TOR project isn't part of Mozilla.

How do I enable hibernation mode?! Have checked the resources out there, no clue still...

So,
I noticed, when I went home for Thanksgiving, that my computer was no longer going into hibernation mode on battery. So I entered "pmset -g" into terminal, to determine what the issue was, and these are my results:
standbydelay         4200
standby              0
womp                 0
halfdim              1
hibernatefile        /var/vm/sleepimage
sms                  1
networkoversleep     0
disksleep            10
sleep                120 (sleep prevented by iTunes, coreaudiod)
autopoweroffdelay    14400
hibernatemode        3
autopoweroff         1
ttyskeepawake        1
displaysleep         15
acwake               0
lidwake              1
I know that standbydelay is the delay for battery sleep, until it goes into hibernation mode. Since I have hibernatemode 3 enabled, it should be fine. However, standby shows a 0 next to it, suggesting to me that hibernation mode has been turned off somehow. I see that autopoweroff (which is the hibernation mode for when the machine is plugged in), shows a 1 next to it, signifying that it is enabled. And...like I would expect seeing these results, my computer hibernates fine after 14,400 seconds when plugged in...yet does not go into hibernation mode EVER when on battery.
How do I turn hibernation mode on for when the computer is on battery? There is a 0 there, so there must be a terminal command to enable/disable it. Not sure how it got jacked up? It's kind of annoying, because it should be entering sleep mode after 4200 seconds to save me battery.
running a mid 2012 non-retina MBP, 10.9.
Thanks!

By what the terminal is telling me is that iTunes is blocking the change. So you would have to disable iTUnes and then activate Hibernation to be able to do this. However I would hesitate in doing this because iTunes is a very active program that downloads tunes to your computer 24-7 because of all those that are free and downloaded to all subscribers.

How to switch 0ff an add-ons compatibility checking while each Firefox starting?

Mentioned problem suddenly appeared after Firefox to 7.0 version upgrade. This constant checking is rather irritating!

Hi konee,
You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

Every time I start Firefox it repeats the add-on compatibility check

I understand the need to check compatibility with newer versions of Firefox. But in my installation (FF4) , it performs this check EVERY time I start up Firefox, and - as the message says - it takes several minutes.
After this check, everything works fine, inclusive all my plug-ins
Previous versions did not have this problem.
I tried already setting all copmpatibility settings to false:
extensions.checkCompatibility.4.0 false
and so on
Is anything else casuing this check at startup of Firefox?

i had this problem too. in your C:\Users\yourname\AppData\Roaming\Mozilla\Firefox\Profiles\yourprofilename directory you will find a file called "user.js". i had upgraded from firefox 6.0.1 to 6.0.2, but for some reason this file did not get updated properly. using notepad i edited this file and changed all references to 6.0.1 to 6.0.2 instead (change your version number as appropriate of course). that fixed the problem for me.

How come every time I open the 4.0 Firefox browser it always does a add on capatibilty check? How do I stop this?

Since upgrading to 4.0 every time I open my browser it keeps doing an add on compatibility check. How do I stop this? Every time it does a check it gets rid of my bookmarks and I have to reload them again, and it also takes me to the Firefox welcome page. How do I stop this as it's a pain in the neck. I hate 4.0 I'm going back to my last Firefox browser as I had very little trouble with it.

Make sure that you do not use the same profile with different Firefox versions.

[SOLVED] Enabling debug for ath9k in compat-drivers-patched from AUR

Wireless card: TP-LINK TL-WN951N. lspci says that it is an Atheros AR5416 adapter [AR5008].
Some background: I'm having the same issues as the OP in this thread, which references this bug report. The problem is that I get a 2000 ms ping every 30 seconds. So 2 seconds of inactivity every 30 seconds. I have the same wireless PCI card, as well. I need to fix this, because it's making online gaming impossible. I should also note that the card is working just fine in Windows 8, however. I am using net-auto-wireless. I have tried using wicd, enabling ath9k's nohwcrypt option, toggling the card's power save, installing the latest compat-drivers-patched from the AUR, toggling different settings in my motherboard's BIOS, and removing the antennae from the card. But nothing has made a significant difference.
I think I'm really close now. I just have to disable ANI. But in order to do that, it seems that I need to enable debugging for ath9k. But this means that I need to either recompile a custom kernel, or somehow enable debug for ath9k in compat-drivers-patched from the AUR. I'd prefer the latter, as that means that I will have a more bleeding-edge driver. That, and I won't have to touch the kernel as much. What I want is described on this page. But it seems too complicated to me. Please let me explain.
I've installed things from the AUR before, as mentioned above, and have properly configured my makepkg.conf for my system. So I'd like to use the CFLAGS and such that I've set. I don't understand how everything works in the PKGBUILD; I don't have much experience with sed and awk and regular expressions, and haven't done much shell scripting at all. It seems that at some point in the PKGBUILD, I need to enable debugging for ath9k before it is compiled. Apparently on the last page I linked to, I need to add:
export CONFIG_ATH_DEBUG=y
export CONFIG_ATH9K_DEBUG=y
export CONFIG_ATH9K_DEBUGFS=y
to some config.mk file. I can only get access to the config.mk file after I install the package with pacman. I've tried adding those lines to my /etc/profile file, and checked, after a reboot, with "set", that those variables are indeed set. But the thing is, with these variables set in /etc/profile, when I run makepkg, makepkg fails with an error 2. I tried again and got the same error. I removed those lines from my /etc/profile, rebooted, tried makepkg again, and everything worked. So putting those lines in my /etc/profile is not the solution, and I feel like I'm doing something very stupid. What am I doing wrong?
I should also note that I've tried to read the wiki page on compiling a custom kernel using ABS, but it seems to just say "get your custom configuration files" and then just continue (so it assumes that I should already be familiar with the configuration part). The PKGBUILD and Creating Packages wiki pages also seem to be a little... too advanced for me at this point in time.
So how do I enable debugging for ath9k in compat-drivers-patched from the AUR? I'd prefer to stick with only editing the PKGBUILD and using makepkg, if possible.
I've really tried to search the web and the arch forums on how to fix this problem myself, but alas, it seems that I need help this time. I greatly appreciate your time for reading my long post.
UPDATE:
I've made a lot of progress. I ended up removing the AUR package with pacman by invoking "pacman -Rsn compat-drivers-patched".
Instructions for [almost] success: First, download compat-drivers-patched from AUR. Then move it to the "builds" directory (or "local", if using ABS). Extract the tarball. After the new directory is created, cd into it. Now here's the important part: run
$ makepkg -so
Then cd into src, cd into the directory inside src, then edit the config.mk file. Make sure these lines are uncommented (or created, if not already there):
export CONFIG_CFG80211_DEBUGFS=y
export CONFIG_MAC80211_DEBUGFS=y
export CONFIG_ATH_DEBUG=y
export CONFIG_ATH9K_DEBUG=y
export CONFIG_ATH9K_DEBUGFS=y
(source)
Now run "cd ../.." to go back up two directories. Now run:
$ makepkg -e
# pacman -U <file that was produced>
And I ran "mkinitcpio -p linux" just in case, but I'm not sure if that is necessary at all. I'm... not touching the kernel, right?
Now I ran:
echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/disable_ani
But bash would say that the file or directory doesn't exist. Even if I prepend it with "sudo", I get the same results. I was only able to get the command to work if I logged in as root. I even put the line in my /etc/profile. The 2000 ms ping every 30 seconds is now GONE. HOWEVER! If I reboot and log in as a normal user, the problem is there again. If I reboot and log in as root, the problem is gone. If I then log out and then log back in as a normal user, the problem does not come back.
So really, I can avoid the problem if I first log in as root, log out, and then log back in as a normal user. But this is a great inconvenience. I would much prefer if I could just log in as a normal user right after boot, and have everything working.
Now, how do I get the command to automatically run at boot as root (without me having to log in as root), and work?
UPDATE 2:
I got it working. Putting the line in /etc/profile is not the solution. I created a custom systemd .service file.
Put this into /etc/systemd/service (name it "disable_ani.service"):
EDIT: Wow. I made a glaring typo here. It should be /etc/systemd/system/disable_ani.service
[Unit]
Description=disable_ani
[Service]
Type=oneshot
ExecStart=/bin/sh -c "echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/disable_ani"
[Install]
WantedBy=multi-user.target
Then make sure to "sudo chmod 755 /etc/systemd/service/disable_ani.service", since root owns this file.
Then run "sudo systemctl enable disable_ani.service".
EDIT: It has been brought to my attention that there is a much simpler way than creating a custom service.
Using a tmpfile:
/etc/tmpfiles.d/disable_ani.conf
w /sys/kernel/debug/ieee80211/phy0/ath9k/disable_ani - - - - 1
Done.
Now ANI is persistently disabled between boots, even if I log in as a normal user right after boot.
Thanks for reading.

So zsh is telling you that the command didn't work, since it claims that there is no such file or directory. I had a lot of trouble with getting the echo command to work, as well. I found that if out of these lines:
export CONFIG_CFG80211_DEBUGFS=y
export CONFIG_MAC80211_DEBUGFS=y
export CONFIG_ATH_DEBUG=y
export CONFIG_ATH9K_DEBUG=y
export CONFIG_ATH9K_DEBUGFS=y
If the first and second line above were not uncommented in the config.mk file, I couldn't leave the last line above uncommented as well, or else makepkg would fail and give me an error. So originally I had only the 3rd and 4th lines above uncommented/inserted in my config.mk. With that configuration, I could not get the echo command to work, no matter what. Have you uncommented or inserted all of the above 5 lines into your config.mk?
After making sure all of the above 5 lines were in my config.mk, the echo command still didn't work, even if I preceded the command with sudo, or entered a su session. Bash would tell me that there was no such file or directory. I found that if I actually logged out of my normal user, and then logged back into the computer as root, the command would work. If your shell does not give you any feedback (particularly, "no such file or directory"), then the command worked. In order to get the command to run every time the computer boots, I used a systemd service, so that the command is issued as root. For some reason, it doesn't work if you put the command into /etc/profile.
Oh, and it would probably be helpful to mention that for the compat-drivers-patched package from the AUR, the PKGBUILD checks to see what your _selected_drivers variable is before compilation. If you set _selected_drivers=ath9k, your compile times will be much shorter.

Firefox loads the "welcome to firefox" along with my homepage (firefox startup page) everytime I start firefox up. It also checks for add-on compatibility at the same time.

My firefox program is regularly updated (automatic update). Normally, after an update, when I start up firefox the "welcome to firefox" (http://www.mozilla.org/en-US/firefox/6.0.2/whatsnew/) with all the new features and stuff display pops up, but only for the first time, together with the add-on compatibility check
This time, however, it just keeps loading everytime I start up firefox. It seems to think that I've just updated all the time. It's not a problem (nothing else is affected), I'm just wondering why this is happening. Suggestions?
I'm running firefox 6.0.2 on a windows 7 platform. No patches or funny stuff added to firefox. Standard players and video/audio encoders.

How do I enable an add-on in Firefox safe mode?

So recently I have had a problem with Firefox crashing all the time and found out it was an add-on that was causing the problem.
I have tried opening Firefox in safe-mode to disable add-ons but they are already disabled, so I want to know how to enable an add-on and then to permanently disable it so Firefox will open normally again. . .
I have already tried to permanently disable all add-ons by using the Firefox options box but nothing happens after I click on the 'make changes and restart firefox' button. After I click it nothing happens and it remains frozen. ([https://support.mozilla.com/en-US/kb/Safe%20Mode Safe mode Window])
So to make things short, how do I enable an add-on in Firefox safe mode?

In Firefox 4 and later [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and also disables hardware acceleration.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
You should still see a Disable button or Enable button (if you disabled them all) in the extension Manager (Tools > Add-ons > Extensions) if you start Firefox in Save mode.

In the Manage Add-ons area of IE 10 three add-ons for "Adobe Acrobat Create PDF" for the Helper, for Selection, and Toolbar. which are labelled as disabled. They are marked to 32 bit and 64bit architecture but when I right click on any of the three add-ons the Enable and Disable selections are grayed out. The more information selection reveals this.

How do I enable these add-ons?

Thanks Bill,
Yes, the plug-ins are there in "Manage Add-Ons>Toolbars and Extensions." But, when I select any of the three Add-ons for Adobe Acrobat, the view that follows has the "enabled" and "disabled" buttons grayed out. No matter how many times I select enable, the add-ons remain disabled.
I think the add-ons only work for 32 bit Internet Explorer, not the 64 bit Internet Explorer, or maybe not even for Windows 8 64 bit.
